摘要：【中文】本发明提供了一株高效氯氰菊酯的降解菌——暹罗芽孢杆菌L5(Bacillus siamensis)，保藏于中国典型培养物保藏中心，地址：湖北省武汉市珞珈山武汉大学，430072，保藏日期2019年11月1日，保藏号为CCTCC M 2019885。本发明菌种对高浓度的高效氯氰菊酯具有一定的降解能力，在纯培养条件下对50mg/L的高效氯氰菊酯的降解率达89.1％。将该菌的发酵液与纳米腐殖酸土壤调理剂混合制备的降解剂能提高对高效氯氰菊酯的降解率，纳米腐殖质表面粗糙，结构较为疏松，孔隙结构发达，这样的结构为菌株L5的固着提供了有力的条件。该菌剂的制备工艺简单，成本低廉，使用方便，具有很好的应用前景。 【EN】The invention provides a degrading bacterium of high-efficiency cypermethrin, namely Siamese Bacillus L5(Bacillus simensis), which is preserved in China center for type culture collection with the address: wuhan university, Lojiashan mountain of Wuhan city, Hubei, 430072, preservation date of 2019, 11 months and 1 day, with preservation number of CCTCC M2019885. The strain has certain degradation capability on high-concentration beta-cypermethrin, and the degradation rate of 50mg/L of beta-cypermethrin under pure culture conditions reaches 89.1 percent. The degradation agent prepared by mixing the fermentation liquor of the strain and the nano humic acid soil conditioner can improve the degradation rate of the beta-cypermethrin, and the nano humic acid has a rough surface, a loose structure and a developed pore structure, so that a powerful condition is provided for the fixation of the strain L5. The microbial inoculum has the advantages of simple preparation process, low cost, convenient use and good application prospect.

摘要：【中文】本发明公开了一种龙虾全生长周期遮蔽装置，遮蔽主体设置在支撑结构上，避免了遮蔽主体与水底进行直接接触，进而防止了养殖过程中水底增加的淤泥将遮蔽主体淹没；遮蔽主体包括底板、侧围板和顶板，底板上置有人工水草，为进入遮蔽主体内的龙虾提供了躲避场所，顶板与侧围板上分别设置多个第一网孔、第二网孔，第一网孔的孔径小于第二网孔，如此当龙虾规格较大不能通过第一网孔时，还可从第二网孔进入遮蔽主体，确保了各种规格大小的龙虾均可顺利进入遮蔽主体内进行躲避，有效地避免了龙虾之间的相互攻击，提高养殖产量，此发明用于养殖设备领域。 【EN】The invention discloses a lobster full-growth-cycle shielding device.A shielding main body is arranged on a supporting structure, so that the shielding main body is prevented from being in direct contact with the water bottom, and further, the shielding main body is prevented from being submerged by sludge added to the water bottom in the breeding process; the shielding main body comprises a bottom plate, a side wall plate and a top plate, artificial waterweeds are arranged on the bottom plate, a shielding place is provided for lobsters entering the shielding main body, the top plate and the side wall plate are respectively provided with a plurality of first meshes and second meshes, the apertures of the first meshes are smaller than those of the second meshes, so that the lobsters can enter the shielding main body from the second meshes when the lobsters are large in specification and cannot pass through the first meshes, the lobsters of various specifications can smoothly enter the shielding main body to be shielded, mutual attack among the lobsters is effectively avoided, and the breeding yield is improved.
